Senior Controls Engineer

Dephy, Inc.•Boxborough, MA

About The Position

Dephy is looking for a candidate who was born to be an engineer: someone that has an urge to understand how things work, and who gets excited when there is no known solution to the problem at hand. We are curious, creative, and passionate engineers looking for a team member to help us tackle challenges at the forefront of wearable robotics. Come help us transition mobility exoskeletons from labs and treadmills to the real world: cities, trails, and mountains. Description of Role Your task is easy to understand but challenging to do well: predict when the user’s foot will next touch the ground and determine how much assistive torque should be applied. There are a few constraints: it has to be done real-time on a small microcontroller, the inputs are noisy, the sensors are limited and imperfect, the terrain, gait and/or gait speed might be changing, the user adapts to your previous actions, and a machine learning algorithm with a 1% false positive rate will result in the user tripping every 100m. As a controls engineer at Dephy you will have a direct effect on deciding the appropriate behavior of our devices while worn by a user. You will do extensive R&D to take data from our sensors, understand what a user is doing, and decide how the motors should respond. This process involves numerous iterations of analyzing data, prototyping simulated solutions, moving simulations to hardware, building custom tools, testing on people, and debugging.

Requirements

Be a good human - get along with the team, build strong working relationships, and execute on Dephy’s Values.
Be a technical leader that loves to solve hard problems
Expertise in at least 2 of the following: Implementation & Architecture: Adjusting and implementing quality final solutions that are computationally efficient, modular, and maintainable. Engineering Principles & Problem Solving: Strong knowledge of topics such as biomechanics, non-classical control, etc which allow for quick identification of problems as well as potential solutions. Management & Planning: Planning a project from start to finish, including creation of requirements, constraints, timelines, and methods to manage risk.
